Arlequin framework for multi-model, multi-time scale and heterogeneous time integrators for structural transient dynamics

► Arlequin coupling performed for beam/3D models for structural dynamic. ► Displacement continuity with multi-scale/heterogeneous time integrators strategies. ► No energy dissipation in the overlapping zones. ► Convergence order: 1-2, as a function of time steps and Newmark's parameters. ► Efficiency/robustness of the method for low and high frequency loading.
